CY62167EV18 MoBL® 16 Mbit (1M x 16) Static RAM 16 Mbit (1M x 16) Static RAM Features automatic power down feature that reduces power consumption by 99 percent when addresses are not toggling. Place the device into standby mode when deselected (CE1 HIGH or CE2 LOW or both BHE and BLE are HIGH). The input and output pins (I/O0 through I/O15) are placed in a high impedance state when: the device is deselected (CE1HIGH or CE2 LOW); outputs are disabled (OE HIGH); both Byte High Enable and Byte Low Enable are disabled (BHE, BLE HIGH); and a write operation is in progress (CE1 LOW, CE2 HIGH and WE LOW). ■ Very high speed: 55 ns ■ Wide voltage range: 1.65 V to 2.25 V ■ Ultra low standby power ❐ Typical standby current: 1.5 A ❐ Maximum standby current: 12 A ■ Ultra low active power ❐ Typical active current: 2.2 mA at f = 1 MHz ■ Easy memory expansion with CE1, CE2, and OE features ■ Automatic power down when deselected ■ CMOS for optimum speed and power ■ Offered in Pb-free 48-ball very fine ball grid array (VFBGA) packages Functional Description The CY62167EV18 is a high performance CMOS static RAM organized as 1M words by 16 bits. This device features advanced circuit design to provide ultra low active current. This is ideal for providing More Battery Life (MoBL®) in portable applications such as cellular telephones. The device also has an To write to the device, take Chip Enables (CE1 LOW and CE2 HIGH) and Write Enable (WE) input LOW. If Byte Low Enable (BLE) is LOW, then data from I/O pins (I/O0 through I/O7) is written into the location specified on the address pins (A0 through A19). If Byte High Enable (BHE) is LOW, then data from I/O pins (I/O8 through I/O15) is written into the location specified on the address pins (A0 through A19). To read from the device, take Chip Enables (CE1 LOW and CE2 HIGH) and Output Enable (OE) LOW while forcing the Write Enable (WE) HIGH. If Byte Low Enable (BLE) is LOW, then data from the memory location specified by the address pins appears on I/O0 to I/O7. If Byte High Enable (BHE) is LOW, then data from memory appears on I/O8 to I/O15. See the Truth Table on page 10 for a complete description of read and write modes.

Test conditions for all parameters other than tri-state parameters are based on signal transition time of 1 V/ns, timing reference levels of VCC(typ)/2, input pulse levels of 0 to VCC(typ), and output loading of the specified IOL/IOH as shown in AC Test Loads and Waveforms on page 5. 17. AC timing parameters are subject to byte enable signals (BHE or BLE) not switching when chip is disabled. See application note AN13842 for further clarification. 18. At any given temperature and voltage condition, tHZCE is less than tLZCE, tHZBE is less than tLZBE, tHZOE is less than tLZOE, and tHZWE is less than tLZWE for any given device. 19. tHZOE, tHZCE, tHZBE, and tHZWE transitions are measured when the output enters a high impedance state. 20. The internal memory write time is defined by the overlap of WE, CE1 = VIL, BHE and/or BLE = VIL, and CE2 = VIH. All signals must be ACTIVE to initiate a write and any of these signals can terminate a write by going INACTIVE. The data input setup and hold timing must be referenced to the edge of the signal that terminates the write. Document #: 38-05447 Rev. *L Page 6 of 16 CY62167EV18 MoBL® Switching Waveforms Figure 4.
